As they were on their way, a second call was received from Bremer Street Food Mart for another reported robbery. The description of the suspect in each of the robberies matched, officials said.

"A guy came through the door, obviously, and said he was going to shoot me if I didn't give him the cash," Bremer Street Food Mart representative Hash Sharma said.

Sharma said he took action.

"I jumped over the counter and went after the guy, and he went out the door," Sharma said. "You're not going to back down to a punk, not in my store anyway."

Meanwhile, a Manchester police officer reported an attempted robbery happening at Uncle Bob's Market. The officer attempted to stop the suspect, who also matched the description of the first two robberies, but the man fled on foot.

"He came to the register and told the guy he had a gun in his pocket," Uncle Bob's Market owner Praidp Patel said.

Authorities said a team of officers chased the suspected burglar until Robert Oxley, 31, was caught.
